ToHashSet<T>(IEnumerable<T>) Method

Creates an hashset from a IEnumerable<T>.

Syntax

[Obsolete("Use ToHashSetEx() extension method instead to avoid conflict with the .NET Fx v4.7.2 ToHashSet() extension method with same signature")]
[Extension()]
public static HashSet<T> ToHashSet<T>( 
   IEnumerable<T> seq
)

Parameters

seq: An IEnumerable<T> to create an hashset from.

Type Parameters

T: The type of the elements of seq.

Return Value

An hashset that contains the elements from the input sequence.

Remarks

The .NET Fx v4.7.2 introduces a ToHashSet() extension method with the same signature. As a consequence this method has been marked as obsolete since NDepend v2018.1.1 and it is advised to use ToHashSetEx<T>(IEnumerable<T>) instead, to avoid ambiguous call error emitted by the compiler.

Requirements

Target Platforms: Windows 11, 10, 8, 7and Linux, MacOS with net10.0, net9.0 or net8.0 installed
